Passivhaus insulation method unveiled in Exeter

One of the first social housing accommodation projects in the UK to feature an innovative heating insulation technique has been unveiled by Exeter City Council.

Three flats located in Rowan House in Sivell Place have been created using the Passivhaus method, Green Building Press reports.

Across Europe more than 20,000 homes, offices and schools are built to this standard that sees heating costs reduced by 75 per cent.

Steve Cains, director of affordable housing at construction services group ISG Pearce, said: "From the technical side of construction, the Passivhaus method is quite different.

"The homes are almost airtight and the air change rate is up to 20 times better than current building regulations."

Following this first phase of construction, 18 more houses in Exeter are expected to be built using the same method.

According to Passivhaus UK, there are 17,000 buildings worldwide that are created to the Passivhaus principles and these typically achieve an energy saving of 90 per cent compared to existing houses.
